After the defeat of Muzan, peace finally returns to the Demon Slayer Corps. With their swords set aside, the surviving Hashira attempt to build normal lives from the ruins of war. Among them, Shinobu Kocho and Giyu Tomioka-once comrades hardened by bloodshed-find solace in each other and start a family. They raise twins: Hitari, who helps Shinobu tend to patients at the Butterfly Mansion, and Hokaru, who trains under Giyu to master Water Breathing. But even in times of peace, shadows linger. Hokaru struggles with his father's quiet intensity, striving to prove himself as a worthy swordsman. Meanwhile, Hitari dreams of tending to the sick, like her mother, but struggles to herbs and anatomy. That yearning changes everything the day she awakens ice powers-a terrifying echo of the Upper Rank Two demon, Dōma, whom Shinobu once fought and Giyu killed. Terrified of hurting her mother, who suffers deep scars and PTSD from that battle, Hitari hides her abilities. Yet her secret grows darker: with each passing night, villagers are found dead, their bodies mangled as if devoured by a demon. The signs all point to something impossible-could Shinobu's own daughter be slipping into the hunger of the enemy they fought so hard to destroy? Now, the Tomioka family stands at a fragile crossroads. Giyu must decide if he will shield his daughter or confront the horrifying truth. Shinobu is forced to face the ice-bound past she tried to bury. And the Hashira, once united to defeat Muzan, may be torn apart by a new, intimate war-one born not from demons, but from within.

Kocho Shinobu and Tomioka Giyu were the definition of an ideal couple-high school sweethearts who carried their love story seamlessly into college. Their relationship was so steady, so unshakable, that people around them often whispered in envy, believing nothing could tear them apart. But during their college graduation party, Shinobu noticed something unsettling: Giyu seemed distant, his warmth slipping away. Days later, just as Shinobu discovered the life‐changing news that she was pregnant, she received a call from Giyu confessing a devastating betrayal. He had gotten her best friend, Hayashi Rinka, pregnant. Heartbroken, Shinobu chose to hide her own pregnancy, carrying the weight of betrayal alone. A year later, she is raising their twins, Giichi and Shiori, working tirelessly as a company assistant to save for med school. Yet fate twists cruelly again when she learns her new boss is none other than Tomioka Giyu. The man she once loved, the father of her children, and the source of her deepest pain. Now, Shinobu must navigate a storm of buried emotions, professional boundaries, and the lingering question of whether love, once shattered, can ever be rebuilt.

"Basically, it's a mafia story featuring our favorite couple, Giyu and Shinobu, with a hint of Obanai and Mitsuri thrown in "You hesitated," she said after a beat, her voice quieter now. "Right before you pulled the trigger. You trusted me." Giyu blinked once. "I didn't hesitate." She tilted her head, studying him. "Of course you didn't."

One a stoic loner of few words, the other a confident queen of intelligence, Giyu Tomioka and Shinobu Kocho were always an odd pair. A chance encounter in high school led to an unlikely friendship that withstood the test of time well into college. But when they're paired up for a lab together, much to both of their dismay, Shinobu suddenly finds herself feeling things she can't seem to identify. With a project to complete and an ocean of built up feelings breaking through all of their barriers, the two must set aside their pride and stubbornness to figure out just what is really going on between them.

A heavy, humanized slow burn, involving Giyushino, Sanekana, Obamitsu, TanKana, Nezuzenu and InoAoi.
